Re: [Elecraft] [K3s] SteppIR Control

[Mike Harris via Elecraft]

KIO3B Interface Option manual:

Monitoring RS232 Data
If you have a device such as a STEPP-IR antenna controller or pc program 
that monitors the RS232 port, you

can continue to use it with the USB port active.
You can connect your device to the RS232 data in two ways:
1. Use the RJ-45 to DE-9S cable plugged into the RS232/USB port on the 
K3 and sense the RS232 signals at the DE-9S connector.


2. If you have a P3 Panadapter connected to the K3, sense the RS232 
signals at the connection to the PC connector on the P3. Never attempt 
to sense RS232 signals at the XCVR connector.

Re: [Elecraft] [K3s] SteppIR Control

[Bob Wilson, N6TV]

Hi John,

If you have *CONFIG: RS-232* set to *USB*, then both K3 serial ports are
fixed at 38400 baud, so you have to use that setting in the SteppIR
controller, and set the radio type to Elecraft (or Kenwood).

A custom cable is required to allow the SteppIR auto-track to work via the
K3 9-pin serial port at the same time.  This is something I implement in my
Serial Box (S-BOX ) offering so that one can use
standard economical serial cables and omit all Y-adapters and expensive
custom SteppIR cables.

The serial cable connection from the SteppIR to the K3S serial port (via
the Elecraft RJ-45 to DE-9F adapter cable, P/N E980297) must make no
connection on Pin 3 (TXD), and Pins 7 and 9 must be shorted.

Finally, a logging program must be actively polling the K3, or CONFIG:AUTO
INF must be set to AUTO 1, or else the SteppIR won't get any frequency data.

If you are also connecting a P3 via the CBLP3Y, then a serial Y-cable or
S-BOX must be connected to the P3 "PC - RS232" port, with one side going to
the CBLP3Y male DE-9 connector, and the other side going to the SteppIR
cable.

Re: [Elecraft] [K3s] SteppIR Control

[John Simmons]

K3 won't do both RS232 and USB at the same time. You'll have to put a 
software shim in your PC to control the SteppIR.

[Elecraft] [K3s] SteppIR Control

[John Reilly]

I have a BigIR which won't connect to my K3 for frequency control It 
worked prior to my move 10 months ago, but not now. I suspect a setting 
problem. I use the K3 USB for rig control and audio, and trying to use 
the RS232 RJ45 plug for the SteppIR. It appears the SteppIR is not 
getting frequency information. How do I configure the Config > RS232 to 
enable data to also go to the both USB and the RS232 port?

Thanks,
